is a specification, reference being had the to the accompanying drawings.

The invention consists in the pe a? C011- struction, arrangement and bination of the various parts, whereb Construction is simplified, cheapen di Ud Improved all as more fully hereinaf l/desclibed.

In the draWiDgs,/Figl1re 1 is a vertical, centml Section-through a vise embodying myinvention. Fig. 2 is a section on line as, Fig..

/11/ Fig. 3 is a section on line z-z, Fig. l,

through the movable jaw, illustrating the means of securing it in position. Fig. 4 is a perspective View ofthe nutsections, their su pporting shaft and operati ng lever= detached. Fig. 5 is a horizontal section on line y y, Fig. 2, illustrating the manner of securing the post of the stationary jaw detachably and adj ust-y ably in position.

A is the stationary jaw of a vise, provided with a transverse aperture or guideway B, in which engages the screw supporting arm C of the movable jaw. This arm has the t-ubular socket D at its outer end in which is detachably secured the circular standard a of the movable jaw E. This standard near its lower end has a lug b adapted to be entered through a vertical slot c in the inner front wall of the socket D and to be locked by a partial rotation beneath an annular shoulder cl at the bottom of the socket.

F is the operating Vscrew for the movable jaw, provided'with the usual handle, or sliding lever at itsouter end and passing longitudinally through the supporting arm C, as plainly shown in Fig. 1.

G is a tubular standard or post formed in tegral with the stationary jaw A and entering the metallic sleeve orsocket H secured in the top I of the table or bench to which the vise is to be attached. This sleeve Hhas an annular flange J at its' top resting upon the bench, the upper face of which forms a turntable for the.

The means of securing these parts together I have shown as comprising the lugs or projections L onth'euter face-of the post G adapted to be 'teed through vertical slots e in the inn r/'face of the sleeve Hand to be locked /leein by engaging beneath the bottom fof that sleeve, as plainly shown in Fig. 2. Upon the upper face of the flange J area series of apertures, in any one of which a spring pin Mon the stationary jaw A is adapted to engage, so as to adjust this jaw in any desired relation to the table. In the same manner I may adjust the movable jaw E in its socket D, by means of a spring pin M engaging in any one of a series of apertures in the post a of that jaw.

O is the upper nut section and O the lower nut section. These n-ut sections are provided with the depending legs P P', separated, as shown in Fig. 2 andr extending through the central aperture in the post Gof the stationary jaw.

Q is a stationary shaft detachably secured in the bifurcated extensions Q of the post G. Ris a weighted lever having its head fitting snugly between the legs of the nut sections and pivoted upon the shaft Q. This shaft passes through vertical slots R R201? the legs of the nut sections, these slots extending respectively above and below the shaft, as plainly shown'in Fig. 2.

S is a horizontal slot extending from a point the Same in the leg of the upper nut section to near the opposite side thereof. S is a similar horizontal slot in the leg of the lower nut section, extending from above the shaft to near the opposite side of that leg. words, these slots are located above and below the shaft in the legs of the nut sections and extend in opposite directions from that shaft ange or bearing K around the post G. The post is detachably engaged with the sleeve.

eration is as follows: The parts being in the potoward opposite edges of the legsyaspl.ai-rely4 ed lever adapted to engage in the horizozfitai 3g slightly to the left hand of the shaft, below In other IOO sition shown in Fig. 1, the weight of the lever will holdthe pins T T in the ends of the horizontal slots and substantially in line with the shaft Q, or slightly on opposite sides of its vertical center, thereby locking the nut sections against vertical movement, except by rocking the Weigh ted lever. drawing down nponthe cord U which rocks the lever upon theshaft Q,and the pins T T moving through the horizontal slots S S will raise the upper section and lower the lower section from the screw, as shown in Fig. 2. The movable jaw can then be adjusted horizontallyavithout turning the screw. When it is desired h't'zmr5pjgeratethe screw, the operator releases the leiten when the Weight will again cause the nut mtons to engage with the screw. The movablejaw E maybe turned at any desired angle to the stationary janT and locked in vits adjusted position `bymeans of the spring pin M. The whole vise may be turned at any desired angle to the bench by releasing the spring pin M from engagement with the notches in the collar J and turn the vise upon the post G to the desired angle where it may be again locked in position by the pin M. This construction of parts simplies and cheapens the vise, besides adapting it to all the requirements.

What I claim as my invention isl. In avise, the combination of the stationary jaW, the movable javs7 adjustably supported therein, a depending cylindrical post This is done by on the under face of the stationary jaw, an aperturedfsleeve to Whichsaid post is adapted to rotatably engage, having vertical grooves in its inner face, lugs on the post. adapted to enter the vertical grooves in the inner face of the sleeve, and to be locked by engaging beneath the sleeve, bythe partial rotation, theV collar J at the top of the sleeve, the bearing K around the post resting on the collar J, and means for locking the stationary jaw in any adjusted position, comprising a spring-actuated pin arranged to enter the apertures in the sleeve substantially as described.

2. In a vise, the combination with the jaws and the screw shaft, of the post G having a bifnrcated extension, a shaft extending across the same, a Weighted lever journaled on the shaft, upper and lower nut sections engaging the screw shaft, the legs P P of the nut section extending down into the post on opposite sides of the lever, having horizontal slots S S therein, extending in opposite directions from `at or near the middle, and central elongated vertical slots through which the shaft passes mdPns 0n opposite sides of the lever engag- 1ng in said horizontal slots, substantially as and fOr the Purpose described.
